Greetings,
I'm trying to confirm what is the proper way to configure internal DNS when the domains are different. I want to configure the internal and external URLs to be the same for the web virtual directories, but as the external address is webmail.somecompany.com, the internal domain structure is corp.ourcompany.com, so if I add an A record for webmail, it will be webmail.corp.ourcompany.com.
How do I need to configure internal DNS so that when internal users go to OWA, etc, it resolves internally and doesn't go out and back in again?
Thanks in advance!
